Universal Circuit Breaker Fixed Type 3200A 3P

Universal Circuit Breaker Fixed Type 3200A 3P are mechanical switchgear that can connect, carry and break the current under normal circuit conditions, and can also connect, carry for a certain period of time and break the current under specified abnormal circuit conditions. Universal circuit breakers are used to distribute electrical energy and protect lines and power equipment from overload, under-voltage, short circuit, etc.

Product application

This type of circuit breaker usually has a steel frame, and all the components are installed inside the frame. It has a large capacity and can be equipped with various functional trip units and a large number of auxiliary contacts. It has a high breaking capacity and thermal stability, so it is often used in places that require high breaking capacity and selective protection.

Q&A

Q：What are the main differences between fixed type and drawer type?

A：The main difference lies in the installation structure and maintenance method. The fixed type is an integrated installation, featuring a simple structure, lower cost and less space occupation. However, when maintaining or replacing it, the upper-level power supply needs to be disconnected. The drawer type supports uninterruptible maintenance and has high flexibility, but it has a complex structure and a relatively high cost.

Q：If the circuit breaker needs to be replaced later, how should it be operated?

A：Fixed replacement requires power-off operation. The process includes: disconnecting the upper-level power supply and confirming there is no electricity → removing the secondary wiring → loosening and removing the circuit breaker body → installing a new body and restoring the connection.
